Bug ID: 107960
Summary: opt-gather.awk seems to ignore lines lines that start
with whitespace
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: documentation
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
echo -e "aaa\n a\n a\na" | awk -f opt-gather.awk > t.txt
and then look at the result of t.txt and notice that only aaa^\a is in the
file.
No error message happens either.
The code in the old opts.sh (which is still the awk script) was broken too.
The problem is here:
/^[ \t]*(;|$)/ { flag = 0; next }
/^[^ \t]/ { if (flag == 0) {
Notice how that the pattern is matching all lines that don't start with white
space.
Also notice how a comment is considered a record seperator too.
Neither of this is documented either.
The documentation for comments is:
Comments may appear on their own line anywhere within the file and are preceded
by semicolons.
Which to mean it in the middle of a record but the code does not allow that.
Have the ability of the "white space" in the front being a comment inside the
record is a nice feature but I do think it should be documented though.
